(CNN) -- Women are getting breast implants in record numbers,
despite the negative publicity the surgery has received in
recent years.

Although scientific studies have failed to show a link
between silicone-gel breast implants and autoimmune diseases
such as lupus and rheumatoid arthritis, the implants have not
been given a clean bill of health.

Thousands of women who claim they suffered health problems due
to implants sued Dow Corning Corp. On Wednesday, the parties
announced they had reached a $3.2 billion settlement.

The deal could give $31,000 to each of 170,000 women, and
would allow Dow Corning to avoid Chapter 11 bankruptcy.

Despite the controversy over the implants, there has been a
275 percent increase in the operations since 1992, when the
U.S. Food and Drug Administration practically banned the use
of silicone-gel implants, because of the safety concerns.

"If we had been talking back in 1992, 1993, I would have said
I did one, maybe two augmentations and took out maybe 50 sets
of implants per year. Now, it's just the opposite," said Dr.
Leroy Young of Washington University Medical Center.

That is the trend in medical practices across the country,
according to the American Society of Plastic and
Reconstructive Surgeons.

Because of the moratorium on silicone-gel implants, the only
option for most women today is to use saline-filled implants.

"The saline implants are very safe. The problem with the
saline is that they, over a lifetime, have a high risk of
leaking," said Dr. Rod Hester, a plastic surgeon.

Doctors say Michelle Pitts is typical of the women who seek
implants. Pitts is 27 years old, in a professional career
and is unhappy with her body image.

"It was for me, personally," said Pitts, explaining her
decision to opt for implants. "I'm not married, so it wasn't
for a husband or significant other. It was just for me,
basically."

Some women are concerned about the possible link between
implants and connective-tissue diseases such as scleroderma.

"A few ask questions about that, but I think that the
epidemiological studies and the other scientific research
that has been done has been very reassuring to women," Young
said.

Still, the question of safety remains unresolved. At the end
of this month, the Institute of Medicine -- a private
research group -- will hold a meeting to review the latest
studies on the issue.
